Flying J Travel Plaza #618, 1501 N. Jack Tone Rd., Ripon CA, 95366 — SR0068444 <br /> transition from double wall fiberglass to black iron occurs below finished grade near the <br /> vent rack. Please provide information on how the continuous monitoring for the vent <br /> piping will be installed for this below grade transition area. <br /> 3. The plans do not include continuous monitoring for the secondary containment of the <br /> product, vent, and vapor piping (vacuum, pressure, hydrostatic). Explain how the plans <br /> will comply with Chapter 6.7 of HSG. <br /> Response received: System is hydrostatic monitored. Refer to the following details for <br /> continuous monitoring illustrations and equipment: 01JPP1.1, 011PP3, 021PP3, 011PP5, <br /> 021PP5. <br /> Upon reviewing the listed sheets it was found that a Bravo Manometer Brine Hydrostatic <br /> Reservoir with a Veeder Root sensor will be utilized with brine filled Ameron Coaxial <br /> LCX 2 inch fiberglass piping. A cut sheet was not provided for this piping, therefore a <br /> determination cannot be made as to which model number is proposed to be installed. <br /> According to the CA State Water Resources Control Board, in the Local Guidance Letter <br /> (LG) 113, acceptable hydrostatic monitoring methods, Ameron Dualoy 3000/LCX for <br /> pressurized primary piping is only allowed to be hydrostatically monitored by pressure. <br /> Also the total length existing product piping is greater than the maximum length of 344 <br /> feet. Please provide information for how the continuous monitoring for the new piping <br /> installed from the injection building to the tee into the existing piping will be meet the <br /> J g gpp g <br /> continuous monitoring q J requirement. Also how is the biodiesel delivered to the injection <br /> building by pressure or suction? If suction, does it meet the definition of"safe suction"? <br /> 4. The secondary containment sump within the injection shed does not contain all of the <br /> piping and attached equipment. Explain how the plans will comply with Chapter 6.7 of <br /> HSC. <br /> Response received: Injection shed foundation and floor is designed to be the <br /> containment with a recessed sloped floor installed to a drain into the sump which is <br /> j monitored by a sensor. <br /> i <br /> Upon reviewing the appropriate sheets, the transition sump in the injection building is a <br /> NEF — National Environmental Fiberglass sump. Please provide a manufacturer cut <br /> sheet, an Affirmative Statement of Compatibility and a third party listing for this sump. <br /> Will the sensor in the sump shut down the pumps in the injection building when an alarm <br /> is trigged? <br /> 5. A completed Unified Program Consolidated Form (UPCF) for Underground Storage <br /> Tank information was not submitted. <br /> Response received: Form to be submitted with this resubmittal. <br /> The completed form has double walled vent piping transition sump checked. A double <br /> e walled vent piping transition sump is not shown on sheet PP1.1. Only a concrete pad <br /> i that supports the black iron piping transition below finished grade. <br /> Also the product piping is listed as a pressurized system. How will the biodiesel piping <br /> have a mechanical line leak detector installed? <br /> 6. Manufacturers' cut sheets for tanks, piping, and equipment (e.g., monitoring equipment, <br /> overspill containment device, overfill protection device, etc.) were not submitted.
